Application filed May 21,

whicha float is employed to operate mechanlsm to close a valve 111 order to cut off the water supply. The object of thepr'esentinvention is to provide an improved flushing device which will operate silently and at the same time give a good flush.

According to my invention, the device consists of achamber divided into a valve compartment and a float'compartment connected by a by-pass opening at the bottom thereof below the valve in the valve compartment, while an outlet pipe of smaller diameter than the opening controlled by the valve leads from the valve compartment. A lever in the valve compartment is controlled by an operating handle and flexibly connect ed to the valve, a pivoted catch above said valve having a hooked end formed with a sloping face to engage a sloping end upon the end of the lever, such catch engaging the lever by gravity when the lever is raised and disengaging the lever as the float rises.

Approved forms of the invention are shown in the accompanying drawings, wherein Figure 1, is a sectional elevation through the device.

Figure 2, is a sectional plan on line AA. Figure 8, is an enlarged View of the valve control mechanism.

Figure 4, shows the apparatus set up in positlon.

Figure 5, is an elevation of a modified form of valve control mechanism.

Figure 6, is a side view thereof.

Referring to the drawings, the device consists of a chamber 1 formed into compartments 2 and '3. From the compartment 2 a down-pipe 13 leads to the pan 12 to be flushed while a water inlet pipe 4 enters the top of the compartment 2 and can be always open thereto. In the compartment 2 is. a

valve seat io controlled by a. valve 6. This,

valve is connected by a chain 7 or other flexible connection to a lever 8fixed upona spindle S'entered in bearings26 in'the walls of the chamber.

One end of the spindle .9 passes through a wall of the chamber and is provided with a handle 11. Suitable stufl- 111g boxes are provided where the spindle passes through the chamber in order to prevent leakage. A catch 14 fixed upon a pin 15 pivoted in the wall of the chamber has a hook like end provided. with a sloping face 16 adapted to engage a'similarly sloping .face upon the end ofthearm 8, the slope being such that when in engagement, as

shown in Figures 1 and 3, the catch 14 will. 1

support the-lever 8 andthe valve 6, but when the catch is lifted to the position shown in. dotted lines in Figure 3, the hooked end will move clear of the end of the lever .8. The catch is connected at. its

forward end by means of a chain 17 or other flexible connection to an arm 18 fixed to a spindle 19 which is mounted in a bearing 20 in the dividing wall between the two compartments, such bearing also forming a stufiing box. The spindle 19 projects into the compartment 3 which forms a float tank. On this end of this spindle another arm 21 is fixed and has pivoted at its end a rod 22 projecting from a float 23. A by-pass 24 for water opens at the bottom of the compartment 2 into the float tank 3.

In operation, the valve 6 is raised to allow water to pass through the valve seat into the flushing pipe 13 by the operator turning the handle 11 on the spindle 9. This operation raises the lever 8 which will move in an are (indicated by the dotted lines in Figure 3) and will raise the catch 14 until the hook-ed portion reaches the position shown in dotted lines in Figure 3, when it will immediately fall by gravity and will be engaged by the sloping face upon the end of the lever 8 as such lever returns downwardly, thus retaining the valve 6 in an open position. As the water passes through the valve a certain quantity is diverted by the bypass 24 into the float tank, the opening into the down pipe being for this purpose less in area than the area of the opening through the valve seat, and raises the float and this water causes the arm 21 to rotate the spindle 19 thereby raising the arm 18 and lifting the catch 14 which, as soon as it is raised, SllfilQlQl'Ltly (see, dottedlines, in Figure 3 willbecome releaseclifi onr the-sloping end of the lever 8 permitting the valve to return to its seat and shut ofi any further supply of Water; Water inthe part 3 then flows through the by-pass 24 and, permits 52 and 6, in place. of the, chain. 17 a cam 25? is mounted on a rod 26. journal'led; in the Walls of the chamber 1' and adapted to be. raised by. the float 23, and forthisxpurpose; the, arm 18: is p'i-votally' connected by link 27. to the cam- 25. As the filo-at. risesthe arm 18, will raise the cam which; in turn. will raise the catch 14s and so release the arm 8 to.- allow the valve 6 to fall;

Suitable means may. be provided to enable the operating 'handle' to. become. free of: the spindle after the lever '8 has been raised sufficiently to engage the catch It sothat the valve cannot beheld open longer than is necessary for th'erequired' amount of flushing water 'to pass through.

Vhile I have described in the foregoing specification the construction of: parts and operation preferred, I do: not limit myself tothe positive terms: employed except such as-the state of the art may require.

WhatI claim is g p 1. A flushing apparatus, comprising, a valve compartment, a valve in the valve compartment, a float compartment, a float in the fi'oat compartment, an outflow pipe connected to the Valve compartment below the valve, a by-pass interconnecting the compartments, an operating handle, a lever in the valve compartment controlled by the operating handle, a flexible connection between the valve and the lever, a pivoted catch positioned above the lever, a sloping faced -ho.oked end on the catch, an end face on the lever cooperating with. the.- sloping portion of. the catch to engage the lever with the catch by gravity when, the lever is sufficiently raised, and connecting meansbetween the catch and the float whereby rising of tlie float causes disengagement of the catch from the lever. v

2. Afl'ushing, apparatus according to claim 1, said. connecting means including, a spindle; passing from the float compartment to the Valve compartment, an arm on the spindle,, a connection between the. arm and thefloat, (a; second arm on the spindle and a fi'exible'connect'ion between. the second.- arm and the catch.

In testimony whereof, I have signed my name to this specification.
